Don’t be afraid to work hard and find out how good you can really be.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

I can is 100 times more important than IQ.

The journey of a thousand miles begins with one step.

The journey of a thousand miles begins with one step. 

Hard work beats talent when talent doesn't work hard.

99% of failures come from people who have the habit of making excuses.

It is never too late to become what you might have been

Start, struggle, fail, fix and learn. Repeat.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Pure mathematics is in its way, the poetry of logical ideas.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.
